Mike Gundogan is a great technician at Princeton air. Very professional and knowledgeable.
Sandra Donnay
Excellent: This was our first experience with Princeton Air. Jermaine was Knowledgeable and professional! We signed up for the membership.
Victoria Orzechowski
The technician who came was Jonathan Redondo. He was very knowledgeable and did an excellent job! I would highly recommend him .
Justin Doran
This is our first time using Princeton Air. Dominic was prompt, professional and knowledgeable. We would recommend Princeton Air to others that need HVAC service or repair.
Megan Casey
Removed one star because they cancelled our original appointment without telling us – which we only found out when no one showed up during our time window. However, we gave them a second shot and for the rescheduled appointment Cruise came to our house and was wonderful! He was incredibly helpful explaining everything to us and was so friendly. We never take the time to write reviews – but appreciated him so much that it was worth the shout out!
Peter Orenzoff

Great job by Ryan Gobel at Princeton Air Conditioning. Ryan figured out a gnarly problem with our older mini-split system, got it working and bought us some time before we’ll need to replace the whole thing. Thanks Ryan!
Roger Perry
Always excellent service with McAllister.
Bruce Tomar
Great job. Worked efficiently. Work area clean
Jeff Stundel
Jose Colon from Princeton Air did an amazing job fixing our high-velocity AC system. He carefully studied the entire system and identified the issue, before walking me through the repair process and associated cost. Jose also gave me valuable pointers on keeping the system in top shape to help avoid breakdowns – but if they happen, I'll definitely be requesting him to do the repairs!
Oleg Vasilevitsky
Amazing service by Cruise from Princeton Air. Very professional, heard the issue, solved my problem, wasn’t pushy on purchasing anything outside of what’s needed, and educated me on how to care for my unit so the same issues don’t happen often. Superb service, thanks Cruise!
Alex Bogorad
Technician that came to rectify earlier issue was excellent! Friendly and knowledgeable and quick. There was no charge because it was under warranty
Louise Sarno
The technician that was sent out yesterday to my house Jose was very nice and pleasant and professional he evaluated the system and told me exactly what needed to be done to resolve and replace the air conditioner and compressor waiting for the quote to be done ✅

Great work Jermaine Richmond! Professional, experienced, and friendly. Everything is working perfectly. You did a great job and I really appreciate your willingness to go the extra mile to help me fix some of the, ahem, errors I made installing my sink. It’s working great!
Georgene Berg
I reached out for a plumber in the afternoon and was told that they would be there in a few hours and they were. Mike the plumber was very nice and professional and got the job done. He had to find the leak cut into the wall and the ceiling replace a broken pipe . He cleaned up. He did not leave any mess. I would definitely recommend the company. Ask for Mike.Our cats liked him too!
